This invention relates to the construction of pin tickets which comprise cards, adapted to receive suitable notations, having fastening means in the form of staples secured to them, the legs of the staples terminating in symmetrical, conical or rounded points free from burs, ragged edges or other roughness which would damage the goods to which the pin tickets are affixed.

In all pin tickets embodying pointed staples which have heretofore been made the staple has been formed from a wire cut at intervals in a plane oblique to the axis of the wire, the wire then being bent into looped form and affixed to a card in such a manner that the legs of the staple would project from the reverse side of the card and usually at right angles thereto. In affixing such pin tickets to the goods the legs of the staples are thrust through the goods and are then bent laterally in such a mannor as to prevent the'pin ticket from being accidentally removed. Pin tickets of this character are usually aflixed to the merchandise by unskilled operatives and the points are bent by the fingers, the Wires are therefore usually of soft steel or brass, usually coated with a non corrosive substance such as tin. In the commercial manufacture of pin tickets the wire is fed continuously to the pin ticket machine, is cut 05 by a diagonally reciprocating knife the plane of which is disposed at an angle to the axis of the wire so that two points are formed simultaneously upon the blank which is substantially bent into the form of a staple and aflixed to the card as aforesaid. This results in the point of the pin being formed at one side of the axis of the'blank;the shearing action frequently leaves irregular ribs or corrugations along the cut surfaces and the end often terminates in a bur. In the use of pin tickets upon delicate fabrics burs or rough edges adjacent to the point of the staples often snag and injure the fibers so that pin tickets of this character are not used upon the highest grades of merchandise particularly silks, satins, laces, hosiery, etc. So far as I am aware no pin ticket having a staple provided with legs terminating in smooth rounded or pointed ends has heretofore been produced.

The object of the present invention therefore is to provide a commercial pin ticket having a staple with a plurality of legs each of which terminates in a smooth symmetrical conical, paraboloidal or rounded point which may be used upon the most delicate fabric without danger of cutting, snagging or otherwise injuring the fibers thereof, the endsbeing substantially symmetrical with the axis of the legs of the staple. I

In connection with this article disclosure will be made of one of the preferred processes by which the article may be produced although it is to be understood that other processes may be utilized in the production thereof.

Other features of the invention will more fully appear from the following description; the accompanying drawing and the annexed claims.

In the drawings: Figure 1 is an elevation of a blank for the staple ofa pin ticket of .the character above described, Fig. 2 is a paraboloidal ends, and Fig. 7 is a view of a staple showing the ends as reduced to conoidal points, Fig, 8 is a perspective view of a portion of the under side of a pin ticket showing the staple with square ends secured thereto, Fig. 9 is a similar View showing the set staple having paraboloidal ends formed thereon by the rocess herein described, Fig. 10 is a similar view showing the set staple having conoidal points formed thereon by the process herein described, Fig. 11 is a View partly in section of one form of apparatus which may be used in the performance of the process of pointing pins and like articles described herein, Fig. 12 is a vertical transverse sectional view of the same. 7

The preferred process by Which perfect staples for pin tickets are formed is as follows. The blank 1 (Fi 1) of the desired length is first cut from t e usual stock, such as a bar or wire to provide a square end, 2. One, or preferably a number, of the several blanks are then secured by suitable means to the positive pole of a source of electric energy such as an electric generator dynamo or storage battery, the opposite' or negative pole of said source being attached to a suitable cup-shaped receptacle adapted to contain, or preferably a trough-shaped conductor nearly immersed in, a chemical solution of a character which will attack the metal of which the blank is composed. The end or ends 2 of the blank are then immersed in the solution to the depth required for the desired tapered point. It will be understood that if a rounded point 3 (Fig. 2) is desired the end will merely rest upon the surface of the liquid whereas if a relatively long taper is required the end will be immersed to a depth slightly less than the desired length of such taper. An electric current of relatively low voltage for example four to six volts, is then turned on and.a vigorous action takes place which rapidly reduces the submerged end or ends to the desired form. By providing a trough-shaped conductor for the negative pole of the electric current and submerging the pins in the vertical axial plane of said trough I have found that the material of the blank will be symmetrically removed and that the length of the taper upon the end will be proportional to the depth of the submergence and the form thereof modified by the proximity of the end of the blank to the bottom of the negative trough shaped conductor.

I have observed that the lines of force of electrolytic action are relatively weak at the surface of the liquid and increase toward the bottom so that as the metal is removed the end gradually assumes a paraboloidal form 4; (Figs. 3 and 6) and if continued a suflicient length of time finally reaches a uniformly tapered conoidal point 5, such as is shown in Figs. 4 and 7. In each case the taper is smooth and symmetrical and is slightly curved in respect to the longitudinal axis or axes of the blank. or of the legs of the blank as the case may be. There is no roughness or unevenness in the ends thus formed due to the displacement of small portions of the metal as is the case in ground or swaged points butthe ends present elemental surfaces in which the molecules of metal retain their original relation to each other and to the axis of the member being treated. By reason of capillary attraction the fluid extends upwardly along the blank a short distance above the plane of the surthe smoothness of the ends, whether rounded or pointed, the pins enter readily into the fabric and can be easily withdrawn without in any Way injuring the fabric or engaging the fibers of the threads of the most delicate material. I have also discovered that the ends of pin ticket staples may be readily rounded or pointed after the same are formed and inserted in. the ticket as shown in Figs. 8, 9, and 10, thus saving a great deal of time in the manufacture of the tickets.

The chem-i cals used in the electrolytic solution must, of course, be varied in accordance with the material, it being desirable if not essential that the electrolyte contain cheminitric and sulfuric acid, suitably diluted is very eflicient and that if a small quantity of lamp black, graphite, cuprous ammonia or other salt of copper is present in the solution all pitting of the tapered end is prevented. It will be understood that the proportions of the chemicals may be widely varied.

The best solution now known tome is made by the mixture of the following solutions: Solution No. 1,-(by weight) water 12 lbs, sulfuric acid 3 lbs, nitric acid 1 1b., nitrate of potash 9; 1b., lamp black 5; oz. Solution No. 2, (by measure) nitric acid, 32 oz., water 16 oz., brass 8 oz., dissolved in same, then mixing equal parts of solution No. 1 and solution No. 2.

For aluminum stock, a solution of caustic potash is very effective. For soft iron or steel a solution of one part sulfuric acid is very effective. A solution comprising nitric acid, one part, nitrate of potash, 1 part, and water 2 parts also gives satisfactory results.

The production of pins or staples in the I manner aforesaid is exceedingly rapid as the may be provided at one end with a binding screw 13 by which it may be connected by a conductor 14L leading to the negative pole of a dynamo or other source of electrical energy.

The pins or other articles to be treated may be supported by any convenient means which will permit their ends to be immersed within the solution within the trough or other receptacle. As shown herein the sup port for the pins comprises a bar 15 provided with a slot 16 in'its upper surface, apertures 17 of suitable size to receive the pins being bored from the bottom of the slot through the bar at suitable intervals along the same. The blanks may be conveniently retained in said bar by a helical spring 18 attached at its ends to the bar and lying within the slot 16 aforesaid, the blanks being passed between adjacent spirals of the spring so that the resiliency of the spring will hold the blanks in place by friction.

Any suitable means may be provided for guiding the bar so that the ends of the blanks will be immersed in the liquid at points equally distant from the sides of the trough. As illustrated herein such guides are in the form of brackets 19 supported upon the ends of the tank and suitably insulated therefrom by insulating plates 20.

In order to provide for the ready removal of the bar and to cause the electric current to pass through the same when it is positioned between the guides, the guides 19 at one end of the trough may be connected in a suitable binding screw 21 directly to the positive pole of the source of electrical energy, said guides being provided with metallic leaf springs 22 or other suitable conductors adapted to engage the side of the bar as it is being thrust between the brackets. The bar may be introduced or removed by hand or any suitable mechanical means such as cams or levers may be employed for the purpose. When the depending ends of the blanks have been tapered as aforesaid the bar may be reversed and the other ends of the blanks tapered in the same manner. 1

It is desirable that the solution be kept at substantially uniform strength in order that the time of treatment of the pins may be uniform. This may be accomplished by providing a reservoir for the fluid mixture and connecting the same with the tank so as to provide for a continuous renewal of the electrolyte in the trough in which the electro-chemical action takes place.

paratus may be employed for carrying out the process above described.

When both ends of theblanks have been tapered as illustrated in Figs. 4 and 5 they may be bent into the form of staples and aflixed to suitable cards by any usual mechanism to form pin tickets such as are illustrated in'Figs. 9 and 10. The pin tickets thus formed are adapted to be applied to the most delicate fabric without snagging or otherwise injuring the fibers of the fabric to which it is attached. It will be readily understood that if desirable the blank may be bent into the form of a staple as illustrated in Fig. 3 and the ends of both legs of thestaple treated simultaneously in the electrolytic solution. Furthermore if desired the unfinished staple may be secured in the body of the pin ticket as shown in Fig. 8 and the legs of the staple thereafter pointed in the manner aforesaid.

It will thus be seen that there is a variety of'ways in which this process may be utilized to taper the ends of staples used in pin tickets.

Having thus described my invention what I claim as new and desire to secure by Let In testimony whereof, I have signed my name to this specification, in the presence of two subscribing Witnesses.
